Starting on a the first real boss

I've been working quite intensely on fully integrating all the monsters I have planned for this level. I'm skipping over a lot of other already mostly finished monsters for now but I wanted to share the concept for the first real boss and one of the two I have planned for this area. Here's a sketch of this cute little guy:

He will be encountered in the emptied out head of the giant skeleton, which is this entire level, so I sketched it on the top of that base artwork. This is supposed to be a not yet fully grown and heavily damaged descendant of Yanos the Sunbleached( that's the name of the level skeleton). The idea here is to have both of his hands do independent attacks. To begin with, I want the skeletal hand to pull smaller creatures from its mouth and place them all around as an attack. Those creatures can't be encountered anywhere else and I had the artwork and a lot of their coding finished for a while. Here's how they look:

I might use this related monster for a variation of the same attack, we will see:

Once you damage the young Yanos enough, he will start using the second arm for large slam attacks and reveal a weakpoint he was covering to make him capturable, if you so wish.

This is a fair bit more complicated than my regular monsters tend to be, but I did some testing and I'm confident I can pull this off.

This is a little mockup of one of the arms being moved manually. I already have a lot of practice moving game objects using code and as you can see the arm bones behave quite realistically if I simply move the hand with this setup. No code required for the rest of the arm, it's just a few Hinge Joints Unity uses with physics simulation turned off.
